When it comes to building a gaming PC or upgrading an existing one, one of the most critical components to consider is the CPU socket. The socket type determines the type of CPU you can install, and with it, the overall performance and capabilities of your system. In this article, we’ll delve into the world of Intel sockets and explore the differences between LGA 1151 and LGA 1150. Which one reigns supreme? Let’s find out!
Understanding the LGA Sockets
Before we dive into the comparison, it’s essential to understand what LGA sockets are and how they work. LGA stands for Land Grid Array, and it’s a type of socket used by Intel for their CPUs. The LGA socket consists of a array of pins that connect with the CPU’s contact points, providing a secure and stable connection.
The LGA socket is responsible for supplying power to the CPU, as well as facilitating communication between the CPU and other components such as the motherboard and RAM. The socket type determines the CPU’s compatibility, so it’s crucial to choose the right socket for your system.
The LGA 1150 Socket
The LGA 1150 socket was introduced in 2013 and was used in the fourth-generation Core i3, i5, and i7 processors. This socket type was designed to support Intel’s Haswell microarchitecture, which focused on improving power efficiency and performance.
Some key features of the LGA 1150 socket include:

What are LGA 1150 and LGA 1151?
LGA 1150 and LGA 1151 are both socket types used by Intel for their central processing units (CPUs). The main difference between the two is the generation of CPUs they support. LGA 1150 was used for 4th generation Core processors, also known as Haswell, while LGA 1151 is used for 5th, 6th, and 7th generation Core processors, also known as Broadwell, Skylake, and Kaby Lake, respectively.
In terms of physical design, both sockets are similar, with the same number of pins and a similar layout. However, they are not compatible with each other, meaning a CPU designed for one socket type cannot be used in the other.
What are the key differences between LGA 1150 and LGA 1151?
The main differences between LGA 1150 and LGA 1151 are the supported CPU generations, as mentioned earlier. LGA 1151 also supports newer technologies such as DDR4 memory, USB 3.0, and SATA Express, which were not available on LGA 1150. Additionally, LGA 1151 has improved power management and increased PCIe lanes, allowing for faster data transfer speeds.
Another key difference is the chipset used with each socket. LGA 1150 used the Z97 and H97 chipsets, while LGA 1151 uses the Z170, H170, and B150 chipsets. These newer chipsets provide improved features and performance, making LGA 1151 a more attractive option for builders and upgraders.
Is LGA 1151 backwards compatible with LGA 1150 CPUs?
No, LGA 1151 motherboards are not compatible with LGA 1150 CPUs. While the physical design of the sockets is similar, the pinout and electrical signals are different, making it impossible to use an LGA 1150 CPU in an LGA 1151 socket. Attempting to do so could result in damage to the CPU, motherboard, or both.
This is because LGA 1151 CPUs require additional power and signal lines that are not present on LGA 1150 sockets. Even if a motherboard manufacturer tried to create a socket that supported both types of CPUs, it would likely be more expensive and complex, making it impractical for consumers.
Can I upgrade my LGA 1150 motherboard to support LGA 1151?
No, it is not possible to upgrade an LGA 1150 motherboard to support LGA 1151 CPUs. The physical design and electrical signals of the socket are hard-wired into the motherboard, making it impossible to modify or upgrade the socket to support a different type of CPU.
Trying to upgrade an LGA 1150 motherboard to support LGA 1151 would require significant changes to the motherboard’s design and layout, including altering the power delivery system, chipset, and other components. This would essentially require building a new motherboard from scratch, making it more cost-effective to purchase a new LGA 1151 motherboard.
What should I consider when choosing between LGA 1150 and LGA 1151?
When choosing between LGA 1150 and LGA 1151, the main consideration is the type of CPU you want to use. If you want to use a 4th generation Core processor, LGA 1150 is the only option. However, if you want to use a newer 5th, 6th, or 7th generation Core processor, LGA 1151 is the way to go.
You should also consider the features and technologies you need. If you want support for DDR4 memory, USB 3.0, and SATA Express, LGA 1151 is the better choice. Additionally, if you want improved power management and increased PCIe lanes, LGA 1151 is the better option.
Is LGA 1151 worth the upgrade from LGA 1150?
If you’re currently using an LGA 1150 system and are looking to upgrade, the answer depends on your specific needs and budget. If you’re happy with your current system and don’t need the latest and greatest features, there’s no compelling reason to upgrade to LGA 1151.
However, if you want to take advantage of newer CPUs, improved power efficiency, and newer technologies like DDR4 memory and USB 3.0, LGA 1151 is worth considering. Additionally, if you’re building a new system from scratch, LGA 1151 is likely the better choice due to its support for newer CPUs and technologies.
Will LGA 1151 be replaced by a newer socket type?
Yes, LGA 1151 has already been replaced by newer socket types, including LGA 1200 and LGA 1700. These newer sockets support even newer CPUs, such as 10th, 11th, and 12th generation Core processors, and offer even more features and technologies.
As new CPUs are released, Intel will continue to develop new socket types to support them. This means that LGA 1151, like LGA 1150 before it, will eventually become outdated and replaced by newer sockets. However, LGA 1151 is still a viable option for those looking to build or upgrade a system with a 5th, 6th, or 7th generation Core processor.
